parameters, feature parameters, and power adjustment parameters of the solar

inverters. If the grid parameters, protection parameters and feature parameters

are incorrectly set, the solar inverters may not connect to the power grid. If the

power adjustment parameters are incorrectly set, the solar inverters may not

connect to the power grid as required. In these cases, the energy yield will be

affected.
